Atharva Veda 7.72: An invitation to Indra

Rise up and look upon the share of Indra fixt by ritual use.
Whether ye poured libation dressed or took delight in it un-cooked.

Libation is prepared. Come to us, Indra: the Sun hath travelled over half his journey.
Friends with their treasures sit around thee, waiting like heads of houses for their wandering chieftain.

Dressed in the udder and on fire, I fancy; well dressed, I fancy, is this new oblation.
Quaff thickened milk of noon's libation, Indra, well pleased, O Thunderer, famed for many an exploit!
